The band performed a faithful rendition of the tune, with frontman Brendon Urie’s acoustic strumming creating a foundation for guitarist Kenneth Harris to recreate – with a few clever tweaks – the song’s tumbling riff and solos. While Panic! At the Disco didn’t inject the “Say It Ain’t So” chorus with its quintessential distorted crunch, Urie’s massive vocals gave the performance a potent extra kick.
